molybdenum and molybdenum-based alloys are widely used.

Chemical industry often use Molybdenum target corrosion resistance. Molten glass can corrode most metals, while the exception of molybdenum and platinum is resistant to the corrosion. Platinum is too expensive, and now tend to use molybdenum or tungsten containing 30% Mo alloy, instead of platinum electrodes for glass melting furnaces. Melting, molten liquid metal bloom: 1059 ℃ lead, 1430 ℃ bismuth, 999 ℃ lithium, 599 ℃ mercury, 899 ℃ of potassium and sodium, 850 ℃ zinc, time, molybdenum corrosion and high temperature strength etc. determines that it is the best material choice, and has been widely applied. In the manufacture of sulfuric acid heat exchangers and valves, molybdenum and molybdenum-based alloys are widely used.
Molybdenum processing industry where more widely used. Molds used under high heat, mechanical alternating stress cracks lead to material fatigue. The thermal expansion coefficient, thermal strength, good high temperature strength of molybdenum or molybdenum alloy, greatly extended tool life. British company GKN watch casting shell and other delicate parts, the life expectancy of up to 5000 times, usually 3000, the bearings used in the production of molybdenum alloy die than the original high-speed steel, bearing steel, tool life increased by 15 times. In isothermal forging hard when the deformation temperature alloy, molybdenum alloy mold can be used at 1200 ℃. Because molybdenum-based alloys, high hardness, high resistance to thermal fatigue strength, commonly used in seamless puncher to make the head and dies, its life than the life of die steel 3Cr2W8V also hundreds of times higher.
Abroad for automotive piston rings, cylinder body wall of molybdenum annual consumption reached more than 600 t. Molybdenum has a high reflectivity of the laser, the laser so that it can not easily be damaged, the United States is using it developed diameter 2.5m, thickness of 13mm laser mirrors. RM Jones (Jouns) that the thermal conductivity of molybdenum and quartz, the thermal expansion properties very close, very suitable for the production of supercomputers heart - a silicon chip wrapper jacket. Molybdenum is a good coating materials, can greatly improve the corrosion resistance of the coating member, to extend component life.
